A main-chain, polydomain, smectic liquid crystalline elastomer (LCE) was prepared by reacting the LC epoxy monomer, diglycidyl ether of 4,4′-dihydroxy-R-methylstilbene, with the aliphatic diacid, sebacic acid. When deformed in uniaxial tension, a “polydomain-to-monodomain” transition took place leading to bulk, macroscopic orientation. With this process was associated a plateau in the nominal s...

twenty six rhizobium strains were isolated from root nodules of sesbania sesban (l.) merr. collected from different regions of andhra pradesh. all the 26 rhizobium strains produced indole acetic acid (iaa), but maximum amount was produced by only five strains in yeast extract mannitol  (yem) medium supplemented with l-tryptophan. the strains were found to elaborate maximum iaa when fed with 2.5...

BACKGROUND Urinary albumin excretion is a sensitive diagnostic and prognostic marker for renal disease. Therefore, measurement of urinary albumin must be accurate and precise. We have developed a method to quantify intact urinary albumin with a low limit of quantification (LOQ). METHODS We constructed an external calibration curve using purified human serum albumin (HSA) added to a charcoal-s...

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors without effective diagnostic biomarkers. This study intended to dynamically analyze serum proteomics in different pathological stages of liver diseases, and discover potential diagnostic biomarkers for early HCC. Patients with hepatitis B virus (HBV) infection, liver cirrhosis (LC), or HCC together with healthy controls (...

PCR assays have proved useful for detecting and characterizing Shiga toxin-producing Escherichia coli (STEC). Recent advances in PCR technology have facilitated the development of real-time fluorescence PCR assays with greatly reduced amplification times and improved methods for the detection of amplified target sequences. We developed and evaluated two such assays for the LightCycler instrumen...

The aims of this study were to determine if the learning curve cumulative summation test (LC-CUSUM) can differentiate proficiency in placing intravenous catheters by novice learners, and identify the cause of failure when it occurred. In a prospective, observational study design 6 undergraduate students with no previous experience of placing intravenous catheters received standardized training ...

introduction: previous studies have shown that stimulation of lateral hypothalamus (lh) produces antinociception. orexin-a (oxa) receptor is strongly expressed in the nucleus locus coeruleus (lc) and orexinergic fibers densely project from lh to lc. in this study, we assessed the role of lc and its oxa receptors in antinociceptive response induced by lh chemical stimulation in the rat. methods:...
